北太平洋中部热带海域深层水文状况分析

AN ANALYSTS OF DEEP-SEA HYDROLOGICAL CONDITIONS IN THE CENTRAL PART OF THE TROPICAL NORTH PACIFIC

通过对“向阳红16”号调查船1986年1月至3月在北太平洋中部热带海域(北纬7°～13°,西经178°～165°)进行综合科学考察时取得的深层水文观测资料的分析,指出该海域平均底层流是从西南流向东北。此结果与Knauss(1962)及Mantyla(1975)的分析结果相符。文中还初步分析了海底地形对深海水文要素分布的影响。

The deep-sea hydrological data, observed by the R / V'Xiangyanghong 16' in the central part of the tropical North Pacific Ocean (178° -165° W, 7° -13° N)during the period from Jan.11 to March 12 of 1 986, was analysed This analysis shows that the bottom water in the area flows from SW to NE, and this conclusion is consistent with the results obtained by Knauss (1 962)and Mantyla (1 975).It also shows that the influence of bottom topography on distribution of the deep -see hydrological elements are very apparent.
